DOOR-HINGE Specification of Letters Patent.

Patented Jan. 26, 1909.

To all whom it may concern:

Be it known that 1, LEwIs WILLIAM HARTSIG, of the city of Chicago, county of Cook, and State of Illinois, have invented new and useful Improvements in Door- Hinges, of which the following is a full, clear, and exact description when taken in connection with the accompanying drawings, which form a part thereof, and in which Figure 1 represents a front elevation of a door and door jamb with hinges embodying the invention, Fig. 2, a top view of the upper hinge shown in Fig. 1, Fig. 3, a transverse vertical section of the same hinge on line 33 of Fig. 2, Fig. 4, a top view of the lower leaf of the upper hinge, Fig. 5, a top view of the lower hinge shown in F ig. 1, Fig. 6, a transverse vertical section on line 66 of Fig. 5, and Fig. 7, a top view of the lower leaf of the lower hinge.

In all figures, similar letters of reference represent like parts.

This invention relates to hinges for doors, and has for its object the utilization of antifriction devices on hinges so as to meet the principal strains or thrust of the door in its movement. To this end, the upper hinge is provided with anti-friction devices so surrounding the pintle of the hinge that they will receive the lateral thrust of the door, as the greater part of the lateral thrust, or strain, that tends to pull the door away from the jamb is present at the top of the door. The lower hinge is provided with anti-friction devices so arran ed as to regeive the downward or vertical thrust of the oor.

To these ends, the invention consists of the several improvements and combinations of arts set forth and claimed hereinafter.

eferring to the drawings for amore particular description, the part designated by the letter A represents a door, and B the door janih and lintel.

O designates the upper hinge and D the lower. The u per hinge is shown formed of two leaves; of which the upper leaf F may l:e fitted into the under side of the lintel of the door and secured therein, and the lower leaf G secured to the upper edge of the door.

1 Each leaf has a lateral offset H for the pintle E which is rigidly secured to the upper leaf F and pro'ects downward through a perforation I in t e lower leaf G. In the lower leaf above the perforation I is seated a socketJ, which is provided with a perforation corresponding to the perforation I for the pintle E. In the socket J surrounding the pintle E are adapted to fit rollers L. The pintle may be held in place in the leaf G by means of a washer M and screw N. 'lhe principal lateral thrust of the door which is inclined to pull the door away from its hinge is at the top of the door, and when the hinge is arranged (as shown in Fig. 1) at the upper end of the door, it will receive the greater portion of this strain or thrust. This thrust is taken up by the pintle hearing against the rollers which surround it laterally in the socket J.

The lower hinge D consists of the two leaves O and P, the leaf O being secured to the door jamb, and the leaf P to the door. 0 carries a lateral offset Q, and the leaf P a lateral offset K. To the offset R is secured a depending pintle S, which is adapted to roject downward through a perforation in the offset Q. Surrounding the intle S are two plates U and V, one of whic fits into a recess in the offset R and another in the offset Q. 'Ihese plates U and V are provided with annular grooves for ball bearings W. A washer X and screw Y hold the pintle within the lateral offset Q and the ball bearings W will take the downward or vertical thrust of the hinge. By this arrangement of hinges, the lateral thrust is taken up by antifriction rollers in the upper hinge at the point where it is greatest, while the vertical or downward thrust is taken up by the ball hearings on the lower hinge.

Having now described my invention, what I claim and desire to secure by Letters Patent, is:

The cornhination with a door; of means for supporting said door consisting of a plurality of hinges secured to the door, one

inge having one leaf secured horizontally to the top of the door, and the other leaf to the frame at ove the door, the other hinge having one leaf secured vertically to the lateral edge 'I he leaf of the door near the bottom thereof, and the other leaf vertically to the frame at the side of the door, both hinges having lateral oil'- sets and pintles in said offsets, the leaves of 110th hinges projecting in sulstentielly the direction of their respective strains, substantially as described.

In witness whereof, I have hereunto set my hand on the 27th day of April, 1906.

LEVV IS WM. HARTSIG.
